Look – Facebook is huge. There are over 1.2 billion active users on the social network, but not everyone uses it the same way.

Today, Business Insider is featuring a video of seven “hidden” tricks within Facebook that can make it more enjoyable than just seeing photos of babies, videos of the latest “Let It Go” cover, or words of wisdom about political developments in your area.

When iOS 7 was released, there was a bug in the geotracking services for apps. When an app was closed, the tracking service was turned off, which was bad news for many apps that relied on the ability to track the phone in the background. The news here is that the bug has been removed.

Who is to thank for helping the bug get fixed? Life360 founder Chris Hulls, who sent a “Hail Mary” request to Apple CEO Tim Cook asking for the bug to be remedied. A few days later, geotracking has been restored. Fantastic news for Hulls and other iPhone users who utilize the tracking service.

Ever wanted to have the ability to communicate with your fellow passengers while on a flight? Virgin America has identified an opportunity to help travelers chat discreetly on their devices while in the sky.

Once upon a time, the signal strength for the iPhone was indicated in bars, as in, “I don’t have any bars of service anywhere.” With iOS 7, bars became dots (or circles if you will). What does a bar or dot mean? How much better is three than two?

Yahoo’s Alyssa Bereznak has documented instructions on how to display your signal strength indicator from as a quantifiable number instead of little dots. After finishing the process, just remember than anything above -80 is good, and anything below -105 is bad.

One benefit? Finding out where the true “dead zones” are at home, the office, the gym, your commute.
